Abstract:The in-depth adjustment of China′s energy structure has put forward new requirements for the high-quality development of the coal industry. Top coal caving mining technology, as one of the main methods for thick coal seam mining, has continuously achieved technological breakthroughs and gradually moved towards high-quality development. This paper systematically analyzes the development history, current technological status, and existing challenges of top coal caving mining technology over the past 40-plus years. In light of the new landscape for coal energy development in the contemporary era, the connotation and requirements for high-quality development of top coal caving are elaborated from five perspectives: high system reliability, zero safety accidents, intelligent intensification, high resource recovery, and green and sustainable mining. Future key research directions for the highquality development of top coal caving mining technology are proposed, including intelligent coal caving, full-process top coal caving, pillarless mining, gangue disposal in goaf, coordinated overburden control, pressure relief mining, and limited-height mining. Furthermore, the main principles for determining the rational mining height in top coal caving are discussed, providing a reference for the high-quality development of top coal caving mining technology.
